In the present study, we collected and investigated spinels from Man Sin deposit in Myanmar using standard gemological testing, microscopic observation, EDXRF, Raman spectrometry. The color observation was performed under various lighting conditions to show differences. A very high Cr/Fe ratio is linked with exceptionally strong red fluorescence. Microscopic spectroscopy identified mineral incl...

The present work describes the facile synthesis of 3-(phenylethynyl)-7H-benzo[de]anthracen-7-one via a Sonogashira coupling reaction. structure synthesized benzanthrone derivative is characterized by 1H- and 13C-NMR spectroscopy high-resolution mass spectrometry. photophysical properties title compound are investigated means UV-Vis fluorescence in various organic solvents.

The production of nuclear fuel used in the research reactor at Instituto de Pesquisas Energéticas e Nucleares (IPEN/CNEN-SP) requires a series of chemical and metallurgical processes. The quality of the end product depends on the control over all the stages of the manufacturing process and over the quality of raw materials employed. In fact, spectrometric methods are increasingly used as quanti...

This paper described the investigation of surface-modified quantum dots (QDs) as a fluorescence probe for the detection of cardiolipin. A single-step method for preparation of non-toxic and photo-stable cadmium telluride (CdTe) QDs capped by L-cysteine in aqueous solution was developed. The prepared QDs were characterized by high-resolution transmission electron microscopy, X-ray diffraction sp...

We studied phagolysosomal pH in alveolar macrophages (AM) using fluorescein-labeled yeast (FYP) and silica particles (FSP) as probes. Fluorescence intensities from the ingested test particles were measured on populations of AM using fluorescence spectrometry and on individual phagolysosomes using fluorescence microscopy. Measurements were performed on rabbit AM, which had been incubated with FY...
